DFB laser / List of 3 manufacturers
What is a DFB laser?
A DFB laser (Distributed Feedback Laser) is a type of laser that is known for its highly stable wavelength, which is crucial in optical communication systems. It uses a distributed feedback structure within the laser cavity to control the wavelength of the emitted light. This structure ensures that the laser emits light at a single narrow wavelength, providing precise and stable optical signals. DFB lasers are commonly used in fiber-optic communication systems, contributing to faster data transmission and improved signal quality.
Application of DFB laser
１．Fiber Optic Communication
DFB lasers play a critical role in long-distance fiber-optic communication systems. They are especially used in data centers and internet backbones to enable high-speed and stable communication.
２．DWDM Systems
In Dense Wavelength Division Multiplexing (DWDM) systems, multiple data channels are transmitted simultaneously using DFB lasers. This improves the efficiency of bandwidth usage and significantly increases communication capacity.
３．Satellite Communication
DFB lasers are also used in satellite communication systems to provide high-quality signals. Their stability is particularly important for long-distance communication in space.
